This patchset provides proof that merging AVSubtitle into AVFrame
is doable and not far away to achieve. It obsoletes the need for
a "subtitle api", as that purpose will be served by the AVFrame
API. It might still make sense to add a number of functions for 
dealing with AVSubtitleRect (e.g. av_subtitlerect_alloc, _free)
as these should probably be ref-counted to avoid copying.
I have added a minimal internal ref counting which serves the current 
use cases, but I'm open to suggestions..
